Beautiful flowers! How long have the flowers been open? The reason I ask is because it looks closely related to Ida ciliata, which (after having been open for a few days) emits a very nice fragrance in the evening. So please test your flowers for fragrance after the sun goes down. Maybe (hopefully!) you will be pleasantly surprised. Even if there's still no scent, congratulations on your flowering plant. It's very pretty.
So very beautiful! I'm having hard times with my Ida ciliata and Ida peruviana. Hard to have them adapted here in Brazil. Congrats on your beautiful flower!
